RAILTIE.

Specication o Letters Patent.

Patented Jan. 5, 1915.

Application filed April 25, 1914. Serial No. 834,395.

To all 'whom t may concern: i

Be it known that I, IsAAc L. LAWSON, a citizen of the United States, residing at Atkins, in the parish of Bossier and State of Louisiana, have invented certain new and useful Improvements in Rail-Ties, of which the following is a specification.

The invention relates to new and useful improvements in rail ties and has for its primary object to provide a metallic rail tie of a simple and durable construction and which is extremely resilient so that shocks and jars incident to the wheels passing from the end of one rail to the other are eliminated.

Another important object of my invention is to provide a rail tie of the character described that will support and enable securing of rails in a reliable manner so that spreading of the rails is prevented and elasticity of the track increased.

A further object of importance is to provide a tie of the character described that will withstand the elements, is durable and is inexpensive to manufacture. 4

With these and other objects in view the invention consists of the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which:l

Figure 1 is a fragmentary plan. view, showing rails mounted upon my improved tie. Fig. 2 is a longitudinal sectional view. Fig. 3 is a transverse sectional view. Fig. l is a side elevation of my tie, showing the rails in section. Fig.' 5 is a side elevation of the tie with one of the side plates removed; and Fig. 6 is a horizontal sectional view.

Referring to the drawings by character of reference the numeral 1 designates as an entirety my improved rail tie that is preferably constructed of some durable metal and has mounted thereon rails 2.

My improved rail tie comprises a rectangular metallic base plate 3 to which are secured vertical and rectangular side plates 4:. The side plates e are preferably secured to the base plate 3 by suitable fastening means but may be formed integral if desired and are slightly extend beyond the ends of the base plates the drawing.- A

A. top plate 5 preferably the same length and shape as the base plate 3 is arranged between the side plates and above the base longer than the base plate to' as shown in Figs. 1 and 6 of plate. Upstanding pins 6 are secured to the base plate 3 at points centrally of and at the ends thereof and extend through openings in the top plate 5. The pins have preferably' countersunk nuts at their lower terminals, the upper terminals have nuts 7 turned thereon. Washers 8 are interposed between the nuts and upper surface of the top plate 5. The pins-are provided with transverse openings adjacent their outer ends through which suitable fastening means 9, preferably cotter pins are inserted to prevent accidental loosening of the nuts. The pins are enlarged intermediate their ends, as at 10, to provide shoulders 11 and 12. The shoulders 11 are designed to engage and act as stops for the plate 5 while the shoulders l2 engage the upper surface of the base plate 8.

End plates 13 are hinged, as at 14, at their upper edges to the ends of the top plate 5, and as shown in Fig. 6, when in operative position are disposed between the extended ends of the side plates l. These plates 13 prevent dirt and other foreign matter from getting into the tie and interfering with the operation thereof.

As a means for providing resiliency for the tie I employ springs 15 arranged between the plates 3 and 5 and fitting at their ends within recesses 16 that are formed in the upper and under surfaces of the plates rail bases and inserted through the top plate 5 and have nuts 18 turned on their lower terminals. Washers and fastening means similar tothe ones 7, 8 and 9 are employed in connection with the rail clamp bolts 17.

lt will be readily seen with reference uto the foregoing description and accompanying drawings that I provide a simpleninexpensive and durable rail tie that`A owing toits great and jars of passing trains and securely hold the rails in place. When trains pass over the rails the springs 15 are compressed and the downward movement of the. plate 5 is resiliency will eliminateishocks plates carried by limited by engagement of the shoulders l1 `i'orzrned on the pins 6. In this connection it Having thus described the invention whatv vis claimed as new, is k 1.l A rail tie comprising a base plate, side the base plate, top plate mounted above the base plate and between the side plates, end plates hinged to the end edges of the top plate, pins secured to the base plate and extending upwardly through the top plate, springs interposed between the base and top plates,and said pins being'` enlarged intermediate their .ends to provide shoulders,

face plate and the other of the shoulders being normally of the top plate.

2. A rail tie comprising a base plate, side plates carried by the base plate, 'a plurality of pins secured to and extending upwardly from the base plate, said pins being enlarged intermediate their ders, certain of said shoulders engaging the upper surface of the bas'e plate, a top plate slidably mounted upon the upper end of the pins, springs interposed between the top and upper edge I have found that the form of my invention, illustrated in the drawings. 1n the above description, as'
